Im technically still a newbie but during my short time I have learned this;
if u are going to give customers that you think may become a potential regular, your telephone number I recommend you get a prepaid phone and use it only for the sole purpose of having your customers contact you about coming in to the club on such and such night.
DO NOT give them your main line that u use for family friends business etc. I made the mistake of doing so and man! He texts me every 5 minutes about being in a relationship and what not, I was trying to be polite and say answers that are vague enough to keep him satisfied but he is getting too clingy so I had to just stop texting him.
Just how I found him there are others that will tip just as good. A big thing one must learn early on in this business, sometimes the money just isn't worth it.
